Obsidian TaskNotes Skill

Manage tasks for the TaskNotes Obsidian plugin directly from Claude Code. All operations route through deterministic CLI tools (mtn for file mode, tn for API mode) with a Python orchestrator handling tool selection and output formatting.

Plugin docs: https://tasknotes.dev/ GitHub: https://github.com/callumalpass/tasknotes

Runtime Configuration (Step 0)

Before any operation, resolve the vault and verify tools:

1. Vault path -- Check $ARGUMENTS for an explicit --vault PATH. If absent, run:

   uv run python scripts/tn_manager.py status --json 2>&1 | head -3
   

   The script auto-discovers the vault. If not found, ask the user for their vault path.

2. Tool availability -- The script auto-detects mtn, tn, and obsidian CLI tools. If neither mtn nor tn is found, run /tn setup to install them.

3. Load reference files (always, regardless of operation):

   • references/frontmatter-spec.md (YAML field reference for task files)
   • references/api-reference.md (HTTP API and CLI command reference)

EXECUTE NOW

Target: $ARGUMENTS

Parse the command:

| Command | Action | |---------|--------| | (none) or status | Show task overview and counts | | create "Title" [opts] | Create a new task | | nlp "natural language" | Create task from natural language | | update "Title" [opts] | Update an existing task | | complete "Title" | Mark a task as completed | | delete "Title" [--force] | Delete a task | | list [filters] | List and filter tasks | | search "query" | Search tasks by content | | today | Tasks due or scheduled today | | overdue | Overdue incomplete tasks | | start-timer "Title" | Start time tracking | | stop-timer | Stop time tracking | | timer-log [--period P] | Show time tracking log | | projects [list\|show NAME] | Project overview | | pomodoro [start\|stop\|status] | Pomodoro timer (API-only) | | install [--source PATH] | Install/update skill into vault | | check-update | Check if installed skill is outdated | | setup | Install/configure CLI tools | | help | Show available commands |

START NOW. Execute the requested operation using the orchestrator script:

uv run python scripts/tn_manager.py --vault <vault-path> <command> [options]

---

Data Strategy

CLI-first, API-enhanced. The orchestrator detects available tools and routes each command to the best one. You do not need to choose manually -- the script handles it.

Tool Fallback Chain

mtn (file mode) → tn (API mode) → direct HTTP API → error with guidance

• mtn (mdbase-tasknotes) -- Reads/writes task markdown files directly. Works offline, no Obsidian needed. Supports NLP creation, CRUD, time tracking, search, projects. Requires enableMdbaseSpec: true in TaskNotes settings.

• tn (tasknotes-cli) -- Talks to the TaskNotes HTTP API. Requires Obsidian running with API enabled. Adds pomodoro, calendar, recurring task management.

• Obsidian CLI -- Quick property reads/writes and vault search when Obsidian is running.

• Direct HTTP API -- Ultimate fallback via urllib. Used when CLIs are unavailable but the API is reachable.

Task File Format

Tasks are standard markdown files with YAML frontmatter stored in TaskNotes/Tasks/:

---
tags:
  - task
title: Review quarterly report
status: in-progress
priority: high
due: 2025-01-15
scheduled: 2025-01-14
contexts:
  - "@office"
projects:
  - "[[Q1 Planning]]"
---

## Notes
Key points to review...

The CLIs handle all frontmatter parsing and generation. Do NOT write task files directly -- always use the orchestrator script or CLI tools.

---

Commands

/tn status

Show an overview of all tasks: counts by status, overdue, and today's schedule.

uv run python scripts/tn_manager.py --vault <vault-path> status

Add --json for machine-readable output.

/tn create "Title"

Create a new task. The orchestrator builds NLP-compatible text from explicit options.

Options:

• --status VALUE -- task status (default: open)
• --priority VALUE -- priority: low, normal, high
• --due YYYY-MM-DD -- due date
• --scheduled YYYY-MM-DD -- scheduled date
• --tags "tag1,tag2" -- comma-separated tags
• --contexts "ctx1,ctx2" -- comma-separated contexts (@ prefix)
• --projects "proj1,proj2" -- comma-separated project names (+ prefix)
• --time-estimate N -- estimate in minutes
• --description "text" -- task body content

uv run python scripts/tn_manager.py --vault <vault-path> create "Design landing page" \
  --priority high --due 2026-04-15 --tags "design,frontend" --contexts "office"

/tn nlp "natural language"

Create a task from a natural language description. Both mtn and tn support NLP parsing with dates, priorities, tags (#), contexts (@), projects (+), and time estimates (~).

uv run python scripts/tn_manager.py --vault <vault-path> nlp \
  "Buy groceries tomorrow high priority @home #errands ~30m"

/tn update "Title"

Update an existing task by title match.

Options:

• --status VALUE -- new status
• --priority VALUE -- new priority
• --due YYYY-MM-DD -- new due date
• --scheduled YYYY-MM-DD -- new scheduled date
• --add-tag TAG -- add a tag
• --remove-tag TAG -- remove a tag
• --add-context CTX -- add a context
• --remove-context CTX -- remove a context

uv run python scripts/tn_manager.py --vault <vault-path> update "Design landing" \
  --status in-progress --priority high

/tn complete "Title"

Mark a task as completed.

uv run python scripts/tn_manager.py --vault <vault-path> complete "Design landing page"

/tn delete "Title"

Delete a task. Use --force to skip confirmation.

uv run python scripts/tn_manager.py --vault <vault-path> delete "Old task" --force

/tn list

List and filter tasks.

Options:

• --status VALUE -- filter by status
• --priority VALUE -- filter by priority
• --tag TAG -- filter by tag
• --context CTX -- filter by context
• --project PROJ -- filter by project
• --overdue -- show only overdue tasks
• --today -- tasks due/scheduled today
• --completed -- include completed tasks
• --where EXPR -- advanced filter expression

uv run python scripts/tn_manager.py --vault <vault-path> list --overdue --priority high

Advanced filtering with --where:

uv run python scripts/tn_manager.py --vault <vault-path> list \
  --where 'due < "2026-04-01" && priority == "high"'

/tn search "query"

Search tasks by title, body content, tags, contexts, and projects.

uv run python scripts/tn_manager.py --vault <vault-path> search "quarterly report"

/tn today

Shortcut for list --today. Shows tasks due or scheduled today.

uv run python scripts/tn_manager.py --vault <vault-path> today

/tn overdue

Shortcut for list --overdue. Shows past-due incomplete tasks.

uv run python scripts/tn_manager.py --vault <vault-path> overdue

/tn start-timer "Title"

Start time tracking for a task.

uv run python scripts/tn_manager.py --vault <vault-path> start-timer "Design landing page" \
  -d "Working on wireframes"

/tn stop-timer

Stop the active time tracking session.

uv run python scripts/tn_manager.py --vault <vault-path> stop-timer

/tn timer-log

Show time tracking log. Use --period to filter: today, week, month, all.

uv run python scripts/tn_manager.py --vault <vault-path> timer-log --period today

/tn projects

List projects or show project details.

# List all projects
uv run python scripts/tn_manager.py --vault <vault-path> projects

# With completion stats
uv run python scripts/tn_manager.py --vault <vault-path> projects --stats

# Show specific project
uv run python scripts/tn_manager.py --vault <vault-path> projects --show "Q1 Planning"

/tn pomodoro

Pomodoro timer (API-only, requires tn and Obsidian running).

uv run python scripts/tn_manager.py --vault <vault-path> pomodoro start
uv run python scripts/tn_manager.py --vault <vault-path> pomodoro status
uv run python scripts/tn_manager.py --vault <vault-path> pomodoro stop

/tn install

Install or update the skill into a vault. Copies SKILL.md, scripts/, and references/ into {vault}/.claude/skills/obsidian-tasknotes/. No symlinks -- all files are copied for Obsidian sync compatibility. The command is idempotent.

uv run python scripts/tn_manager.py --vault <vault-path> install

Use --source to specify a different skill repo location:

uv run python scripts/tn_manager.py --vault <vault-path> install --source /path/to/skill-repo

/tn check-update

Check if the installed skill in the vault is outdated compared to the source repo.

uv run python scripts/tn_manager.py --vault <vault-path> check-update

/tn setup

Install and configure the CLI tools. Detects what's already installed and only installs what's missing.

uv run python scripts/tn_manager.py setup

/tn help

Show available commands and options.

uv run python scripts/tn_manager.py help

---

Working with the Obsidian CLI

When Obsidian is running, the CLI can supplement script operations:

# Search for tasks across the vault
obsidian search query="quarterly report" path="TaskNotes/Tasks"

# Set a property on a task file
obsidian property:set name="status" value="done" path="TaskNotes/Tasks/MyTask.md"

# Read a property
obsidian property:get name="priority" path="TaskNotes/Tasks/MyTask.md"

When to use CLI vs scripts:

• Obsidian CLI: quick single-property reads/writes, vault-wide search
• Scripts (tn_manager.py): all CRUD, bulk operations, filtering, time tracking

---

Task Matching

Both mtn and tn support title-based task matching:

1. Exact case-insensitive match
2. Substring/fuzzy match if no exact match
3. Multiple matches: the CLI lists them and asks for clarification
4. No match: reports "Task not found"

---

Error Handling

| Situation | Response | |-----------|----------| | Neither CLI installed | Prompt to run /tn setup | | mtn missing, tn available | Use tn (API mode), note offline limitation | | tn missing, mtn available | Use mtn (file mode), note API features unavailable | | API not available (API-only ops) | Error: "Requires Obsidian running with API enabled" | | Task not found | Report with suggestions | | Multiple title matches | List matches, ask user to be specific | | mdbase spec not enabled | Guide user to enable it in Settings | | CLI command fails | Print stderr, suggest troubleshooting | | Vault not found | Ask user for vault path |

---

Prerequisites

• TaskNotes plugin installed and enabled in Obsidian
• Bases core plugin enabled in Obsidian
• mtn (npm install -g mdbase-tasknotes) for file-mode operations
• tn (see /tn setup) for API-mode operations
• For mtn: enable "mdbase spec" in TaskNotes Settings -> Integrations
• For tn: enable "HTTP API" in TaskNotes Settings -> Integrations

---

Integration Notes

• This skill is independent of the obsidian-project-planner skill. TaskNotes and Project Planner serve different purposes and manage different data.
• The skill uses the Obsidian CLI skill for CLI operations when beneficial, but does not depend on it.
• Task tags created by this skill are Obsidian frontmatter tags (e.g., #task), not a separate tag system.

---

Installation & Updates

Install skill into a vault (copies files, no symlinks):

uv run python scripts/tn_manager.py --vault /path/to/vault install

Update the skill (pull latest from repo, then re-install):

cd /path/to/obsidian-tasknotes-skill
git pull
uv run python scripts/tn_manager.py --vault /path/to/vault install

Check for updates:

uv run python scripts/tn_manager.py --vault /path/to/vault check-update

Install CLI tools (separate from skill installation):

uv run python scripts/tn_manager.py --vault /path/to/vault setup

What gets installed into the vault (via install):

• SKILL.md -- skill definition
• scripts/ -- Python orchestrator (common.py, tn_manager.py)
• references/ -- frontmatter spec and API reference
• .installed-version -- version marker for update checks

What gets installed globally (via setup):

• mdbase-tasknotes (npm global) -- provides mtn command
• tasknotes-cli (git clone + npm link) -- provides tn command
• Configuration for both tools pointing to the vault
